srras COMBINED SIDE HARROW AND CULTIVATOR.

Application filed June 15, 1920. Serial No. 389,083.

To all whom it may concern:

I Be it known that I, EDWARD ALroRD HIN- TON, a citizen of the UnitedStates, residing at Liberty, in the county of Amite and State ofMississippi, have invented a new and useful Combined Side Harrow andCultivator, of which the following is a specification.

My invention relates to combined harrows and cultivators, especiallyuseful where inequalities of the soil render existing harrows andcultivator inefficient; and the objects of my invention are, first, toprovide a structure capable of working contiguous soil located atdifferent altitudes efficiently; second, to provide for easy, manualoperation of the structure; third, to provide for economicalconstruction of the device; fourth, to insure ready replacement of worn,unserviceable parts; and, fifth, to attain these ends with structuralsimplicity and economy.

I accomplish these aims by the mechanism illustrated in the accompanyingdrawings, wherein:

Figure 1 represents a side elevation of the structure embodying myinvention.

Figure 2 is a bottom plan View thereof.

Figure 3 is a top plan view thereof.

Figure 4 is a rear elevation thereof.

Figure 5 shows the bottom and side views of plate 4.

Figure 6 shows the bed plate, with angular slot, permitting oscillationsof the mecha nism.

The same designations indicate corresponding parts in all the views.

The cultivator 1 consists of a draft pole 3, having guide handles 2sustained by brace rod 21 and counterpart stays 22. The plate 23,secured to the upper surface of the beam 3, is perforated to pass ascrew 13, held in place by wing nut 14, which also penetrates the beam 3and the plates 4: and 5 attached to the under surface thereof. The plate4 has a hole 26 to pass screw 13 and two projections or lugs 17. Theplate 5, located below plate 4, has a central angular slot 15 whichreceives the lower terminal of the screw 13; it also has arms perforatedby holes 20; it also has two left hand recesses 16 and two right handrecesses 17 wherein the projections 17 alternately rest, according asthe screw 13 is one leg of the angular slot 15 or the other. Counterpartpivoted frames 7, holding rigidly two series of teeth 6, are secured onone side to the under surface of the plate 5 by pivots 8, so that thetwo frames can assume different relative p0- sltions to the plate 5, andbe locked in each position by alternately securing the hooked end of theconnecting rod 11 in the holes 10 of plate 9 on the under surface of thebeam 3,

or in the holes 20 of the arms of plate 5. The connecting rod 11, havingturnbuckle 25, is pivotally secured by nut 12 to the frame 7 from whichthe teeth depend. The stirrupshaped frame 19 is united to the undersurface-of the frame bars 7 by screws 24, passing holes in the innerterminals of the frames 7, wherein struts 18 are pivotally secured,aiding the reciprocating movements of the frames 7.

It will be perceived that the structure above described and illustratedenables the combined harrow and cultivator to adapt itself automaticallyto inequalities in the ground being worked, by the ability of the teethframes to oscillate correspondingly, as permitted not only by thepivotal joinder of the teeth to the draft beam, but also by the slottedplate 5 which allows reciprocations of the threaded screw 13.

The operation of my device is as follows: When it is desired tocultivate a narrow strip of ground, owing to irregularities andundulations of the soil, the hooked ends of the rods 11 are inserted inholes 10 of plate 9, the turnbuckle 25 permitting a rigid j oinder. Whena wide strip of earth is to be cultivated the ends of rods 11 arewithdrawn from holes 10, and, the hooked ends are inserted inperforations 20 in the arms of plate 5; the angular slot 15 in the sameplate permitting the altered juxtaposition of parts. The bars 7, holdingthe teeth, being pivotally joined to the plate 5, enable the teethalternately to cover a Wide and narrow strip of earth, according to theexigencies of the situation.

Having thus fully described my improvements, what I claim is:

The combined side harrow and cultivator herein shown and described,consisting of a perforated plate attached to the upper surface of thedraft beam; a screw passing therethrough secured removably by a wing 105nut; a plate attached to the under surface of the beam, perforated topass said screw, and having depending projections engaging alsion andcontraction; enabling-cultivation-of strips of ground of variable Width;and the adjustable connecting rods whereby the alterabilityl of theteeth frames is effected, 10 for the purposeslherein fully shown anddescribed.
